HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 444,667, dated January 13, 1891. Application iiled J une 13, 18.90. Serial No. 355,356. (No model.)

To all whom it may concern: The shaft O is screw-threaded, as shown, and Beitknown thatI,FRANKDONALD,of Deniis provided at its outer end with a laterallyson, in the county of Grayson and State of extending varm D, the free end of which is pro- Texas, have invented a new and Improved vided with an inclined portion D', adapted to 55 Hay-Press, of which the following is a full, operate the gear-shifting mechanism, as declear, and exact description. scribed below.

My invention relates to improvements in The gear-wheel E is mounted on the shaft hay-presses; and the object of the invention C, between the keeper O and one of the bearis to produce a hay-press of simple construcings c, said gear-wheel having an internal 6o to tion that will Work easily and rapidly, that screw-thread fitting the thread of the shaft O, will operate in such a manner that the hay so that when the wheel is turned in one dicannot clog in the press, and in which the rection the shaft C Will be forced into the plunger or follower Will be automatically repress-box, thus pushing the follower B thereciprocated byacontinuons motion of the main in, and when the gearwheel E is turned in 6 5 pulley. l the opposite direction the shaft and follower To this end my invention consists in cerwill be retracted.

The pressboxA is also provided at top and bottom with projecting portions fuvhich also serve to prevent the hay from working back in the pressbox, and with vertical strips A?, which limit the outward movement of the doors M. Pivoted on a horizontal shaft nin the upper portion of the press-box and at a point near the end of the follower-stroke is a sleeve o, carrying radially-extendingknives o', so that as the follower and hay are forced into the press the knives will revolve and cut the hay which extends over the top of the follower and prevent the same from clogging.

A horizontal shaft P extends across the top and bottom of the rear portion of the pressbox, one end of each shaft being provided with a nut p, and the opposite end of each shaft pivoted to the lever q, which has a eamlike projection q' thereon, so that by moving the lever in one direction the cam q' will be brought next the press-box, thus forcing the sides of the box inwardly, and by moving the lever in the opposite direction the cam will be turned outwardly and the sides of the press-box allowed to spread. It will thus be seen that the tension maybe very quickly and easily regulated, and that by forcing the sides of the press-box inwardly the divisionblocks, which are such as are ordinarily used in a hay-press, may be tightened and held in a desired position.

Spools of wire S are mounted in suitable supports at one side of the frame A, so that the wire may be convenient for use and may be thrust through the frame A, so as to bind the bales therein.

The press is operated as follows: Any suitable power is applied to the pulley J, and hay is inserted into the press-box through the top in the usual manner. As shown in the dra-wings, the gear-wheel K is in engagement with the pinion F2, and the movement of the gearwheel turns the shaft F, pinion F', gear-wheel E, and screw-shaft C, thus pressing the follower B into the press-box. As the shaft C and follower B move in the press-box, the inclined face D' of the arm D will be brought in contact with one of the inclined faces G', thus tilting the frame and throwing the gearwheel K into engagement with the pinion F'. This reverses the movement of the shaft F and retracts the follower B. It will also be seen that by actuating the lever L and rod L the frame G may be tilted at any time and Pivoted in opposite sides the movement of the follower regulated at will.

In constructing the press thc press-box A should belong enough to contain several bales of hay, and the bales in the rear end of the press-box will thus serve as abutments for the succeeding bales.

llaving thus described my invention, I claim as new and desire to secure by Letters Patent* l. A hay-press comprising a frame or pressbox, a plungeradapted to reciprocate therein, a screw-shaft mounted in suitable supports and connected with the plunger,a gear-wheel mounted on the screw-shaft and having an internal thread to fit the thread of the shaft, a shaft mounted in suitable supports nearly parallel with the screw-shaft and carrying pinions at each end thereof, one of said pinions meshing with the gear-wheel on thc screw-shaft, a gcarwheel mounted on a suitable shaft at right angles to the pinion-shaft, and means for bringing said gear-wheel alternately into engagement with the pinions, substantially as described.

2. A hay-press comprising a press-box, a plunger adapted to reciprocate therein, a screw-shaft mounted in suitable supports and connected with the plunger, a gear-wheel mounted loosely on the screw-shaft and having an internal screw-thread to fit the thread of the shaft, a shaft mounted in suitable supports nearly parallel with the screw-shaft and carrying' pinions at each end, one of which meshes with t-he gear-wheel of the screw shaft, a horizontally-tilting frame mounted on suitable supports, a shaft mounted on said frame substantiallyat right angles to the pinion-shaft, said shaft having at its outer end a driving-pulley and at its inner end a gear-wheel adapted to engage the pinions, and means for automatically tilting the frame and bringing the gear-wheel mounted thereon into alternate engagement with said pinions at each end of the plunger-stroke, substantially as described.

3. In a hay-press, the combination, with the plunger havin ga sidewise-extending arm, a screw-shaft connected with the plunger and having a sidewise-extending arm, the pinion E on the screw-shaft, the shaft F, and pinions F and F2, of a tilting frame adapted to be engaged by the arms of the plunger and screw-shaft, the shaft L, and gear-wheel K, substantially as described.
